The Thoroughbred is a horse breed best known for its use in racing. Intense selection for speed and stamina has led the Thoroughbred to develop energy-efficient muscles, with a high aerobic capacity relative to skeletal muscle mass. Dr Mary F. Rooney and her colleagues from University College Dublin and Trinity College Dublin, Ireland, investigated how different myostatin genotypes in equine muscle are correlated with muscle fibre composition and, ultimately, influence the race distance aptitude of the Thoroughbred horse.

The UNAIDS estimates that 38 million people currently live with human immunodeficiency virus (HIV) infection. Combination antiretroviral treatment has had great success in saving lives but is also associated with numerous medical and public health challenges. Vaccination remains the best and most cost-effective option for controlling HIV infection across the world. Professor Tomáš Hanke jointly from the University of Oxford, UK, and Kumamoto University, Japan, designs vaccines and coordinates clinical programmes testing the most advanced vaccine candidates developed by his team in the UK, Europe, USA and Africa.

Sweet basil is among the most popular and economically important culinary herbs, but by 2010, US production began to feel the impact of a newly emerging destructive disease: basil downy mildew. At that time, no sweet basil varieties were resistant to basil downy mildew and growers began relying heavily on fungicide application to avoid devastating crop losses. Dr James Simon at Rutgers University had been researching basil for 25 years and was eager to tackle this problem. Eight years later, Dr Simon’s team is proud to have successfully developed 12 new downy mildew resistant varieties of sweet basil and two varieties resistant to fusarium wilt disease.

More than 80% of agricultural land in the US is managed by farmers whose operations fall between small-scale farms with direct access to local markets, and larger industrialised farms. These farmers in the ‘middle’ increasingly struggle to find a place within the larger food production system. Through his work as part of the ‘Agriculture of the Middle’ Initiative, Dr Thomas Gray of the Rural Business-Cooperative Service at the US Department of Agriculture has been studying different types of cooperative structures for best adaptability to socio-economic and food consumption patterns for mid-size farm survival.

Young people can often be discouraged from engaging with STEM subjects because they seem to have little obvious connection to their everyday lives. At Winston-Salem State University in North Carolina, an innovative program led by Dr Tennille D. Presley, is seeking to engage students by combining physics and biology with an art that is central to many students’ social lives: music. Early results from the program suggest that it has been successful in making science exciting and showing students that physics is involved in everything.
